Definitions

  • This invention relates to incremental redundancy or hybrid ARQ Type II or III retransmission techniques in mobile communications systems and is particularly applicable to cellular systems.
  • ARQ Automatic Repeat request
  • FEC Forward Error Correction
  • SAW stop-and-wait
  • SR selective-repeat
  • a data unit (PDU) will be encoded before transmission.
  • PDU data unit
  • three different types of ARQ are e.g. defined in S. Kallel, R. Link, S. Bakhtiyari, IEEE Transactions on Vehicular Technology, Vol. 48 #3, May 1999 "Throughput Performance of Memory ARQ Schemes”.
  • This invention is related to Type II and Type III schemes, where the received (re)transmissions are combined.
  • These schemes can be seen as a link adaptation technique, since the redundancy can be adapted according to the channel conditions as for example described in 3GPP TSG RAN, "Physical Layer Aspects of High Speed Downlink Packet Access TR25.848 V5.0.0” and in Amitava Ghosh , Louay Jalloul, Mark Cudak, Brian Classon, "Performance of Coded Higher Order Modulation and Hybrid ARQ for Next Generation Cellular CDMA Systems", Proceedings of VTC 2000.
  • AMC adaptive modulation and coding
  • Modulation Coding Scheme MCS
  • Packet size depends on MCS level and number of orthogonal codes allocated for a particular transmission. We will refer to MCS level and number of codes as Transport Format and Resource Combination (TFRC).
  • TFRC Transport Format and Resource Combination
  • TTI Transmission Time Intervals
  • bit combining method also influences the robustness of packets to the transmission errors.
  • Incremental Redundancy provides more reliable transmission at the expense of increased soft buffer memory requirements.
  • UMTS Universal Mobile Telecommunication System
  • the network elements are functionally grouped into Core Network (CN), UMTS Terrestrial Radio Access Network (UTRAN) and User Equipment (UE).
  • CN Core Network
  • UTRAN UMTS Terrestrial Radio Access Network
  • UE User Equipment
  • UTRAN is responsible for handling all radio-related functionality
  • CN is responsible for routing calls and data connections to external networks.
  • the interconnections of these network elements are defined by open interfaces as can be seen in the Figure. It should be noted that UMTS system is modular and it is therefore possible to have several network elements of the same type.
  • FIG. 2 illustrates the current architecture of UTRAN.
  • a number of RNCs Radio Network Controllers
  • lub wired or wireless links (lub) to the CN.
  • Each RNC controls one or several base stations (Node Bs) which in turn communicate via wireless links (not shown) with the UEs.
  • High Speed Downlink Packet Access is a new technique that is standardised (see for example, 3GPP TSG RAN "Physical Layer Aspects of High Speed Downlink Packet Access TR25.848" V5.0.0 or 3GPP TSG RAN TR 25.308: “High Speed Downlink Packet Access (HSDPA): Overall Description Stage 2", V5.2.0). It shall provide higher data rates in the downlink by introducing enhancements at the Uu interface such as adaptive modulation and coding. HSDPA relies on hybrid Automatic Repeat Request protocol (HARQ) Type II/III, rapid selection of users which are active on the shared channel and adaptation of transmission format parameters according to the time varying channel conditions. The invention is particularly applicable to HSDPA but is not restricted to this system. Therefore the data transmission does not necessarily have to be in the downlink nor does it depend on a particular radio access scheme.
  • HARQ hybrid Automatic Repeat Request protocol
  • the User Plane Radio Interface Protocol Architecture of HSDPA is shown in Figure 3.
  • the HARQ protocol and scheduling function belong to the Medium Access Control High Speed (MAC-hs) sublayer which is distributed across Node B and UE.
  • MAC-hs Medium Access Control High Speed
  • RLC Radio Link Control
  • Parameters of the protocols are configured by signalling in the control plane. This signaling is governed by a Radio Resource Control (RRC) protocol.
  • RRC Radio Resource Control
  • RAB Radio Access Bearer
  • Each RAB is subsequently mapped to a service offered from MAC layer. This service is referred to as Logical Channel (LC).
  • LC Logical Channel
  • the performance of high speed packet transmission may depend on technical characteristics of the mobile UE capabilities. These could be signaled from the UE entity to the RNC entity during connection establishment using the RRC protocol.
  • Radio Link Control A scheduler is located in Node B so that retransmissions can be rapidly requested thus allowing small delays and high data rates.
  • a physical channel is used to transmit data to a receiver.
  • HS-DSCH High Speed - Downlink Shared Channel
  • UE1 User Equipment
  • Tx a data packet A to the UE1.
  • Rx User Equipment
  • UE1 will demodulate and decode the packet A.
  • an ACK or NAK will be sent (depending on if the packet A has been received correctly or not).
  • UE1 sends a NAK assuming that Packet A has not been received correctly. If the NAK has been received and decoded correctly by the transmitter (t propa introduced once again by the radio channel), the transmitter can decide to resend the data packet after a processing time t TX process .
  • the number of data packets that have to be stored depends on the number of simultaneously active HARQ processes.
  • a high level architecture of HSDPA Base Station is depicted in Figure 5. It is assumed there are #1...# X different data flows (logical channels) with data packets to be transmitted from the Node B to the User Equipment (UE).
  • the set of HARQ transmitting and receiving entities, located in Node B and UE respectively, will be referred to as HARQ processes.
  • the maximum number of HARQ processes per UE is usually predefined.
  • QoS Quality of Services
  • the scheduler will consider these parameters in allocating resources to different UEs.
  • the scheduling function controls the allocation of the channel (HS-DSCH) to different users or to data flows of the same user, the current MCS level in one TTI and manages existing HARQ instances for each user.
  • a data flow or even a particular packet of a data flow may have a different priority. Therefore the data packets can be queued in different priority queues. Different data flows with similar QoS requirements may also be multiplexed together (e.g. data flow #3 and #4).
  • HS-DSCH that carries the data packets there is control data which is mapped onto a High Speed - Shared Control Channel (HS-SCCH). This could carry data such as the HARQ process ID, the modulation scheme, code allocation, transport format etc. that is needed by the receiver to correctly receive, demodulate, combine and decode the packets.
  • the scheduler decides which of the N HARQ processes shall be used for transmission.
  • Each HARQ process can have different window sizes.
  • HSDPA there is only a single HARQ process scheduled each TTI and each process works as a SAW protocol which corresponds to selective repeat ARQ with window size 1.
  • TTI transmission time intervals
  • the HARQ process number as well as the sequence number has to be signalled separately to allow a proper combining even if the packet is not received correctly.
  • the 1 bit sequence number is called New Data Indicator (NDI). Each time a new packet has been sent, the NDI is incremented.
  • the HARQ process ID and the NDI are signalled on the HS-SCCH.
  • each packet has a Transmission Sequence Number (TSN) for reordering of correctly received packets.
  • TSN Transmission Sequence Number
  • This information is signalled inband in an header that is part of the packet.
  • the TSN is increased for new each packet that is send by the transmitter.
  • the receiver will check the TSN after successful decoding of an packet and deliver the packet only to higher layer if there is no previous packet of that data flow missing.
  • the received packet will be stored in the reordering buffer to wait for outstanding packets and to ensure in sequence delivery to higher layer. If the reordering buffer is full because the receiver is waiting for an outstanding packet for a long time the transmission must be stopped to avoid dropping or overwriting of packets. This situation is called stalling and can reduce the data throughput significantly.
  • the stalling can be mitigated by different means such as time out timer, window forwarding etc.
  • the receiver recognizes that it will not receive certain packets anymore and continues operation.
  • a retransmission has a higher priority compared to new transmissions to reduce overall delay.
  • a packet will be scheduled every 6 TTI for successive erroneous decoding.
  • a basic method is to adapt the number N of HARQ processes or the window size of a ARQ process to the round trip time.
  • a practical implementation in this case would be an N channel Stop-and-Wait ARQ process.
  • Continuous transmission while considering the round trip delay can be assured by switching between the HARQ processes every TTI.
  • a new transmission can be initiated on a HARQ process at any time even though there is a retransmission pending for that process. This will cause the UE soft buffer of the process to be flushed.
  • the number of HARQ processes is chosen according to the round trip delay to provide continuous transmission while minimizing the number of processes.
  • the window size be selected according to the RTT for window based ARQ mechanisms. Since the RTT can vary during transmission so the initial configuration may not be optimum anymore.
  • a scheduler may preempt a certain transmission according to QoS attributes (priority, delay requirement, guaranteed bit rate and other parameters) known by the scheduler.
  • QoS attributes priority, delay requirement, guaranteed bit rate and other parameters
  • the formulation preemption of higher priority data over lower priority data will be used in the following although the reason for preemption may be a QoS attribute other than priority (e.g. delay requirement).
  • the transport format e.g. transport block size
  • resource combination e.g. number and index of codes
  • different MCS levels and thus packet sizes can be scheduled.
  • each HARQ process is assigned a certain amount of soft buffer memory for combining the bits of the packets from outstanding retransmissions.
  • the reordering buffer provides the in-sequence delivery to RLC sublayer.
  • the reordering queue is tied to a specific priority.
  • the available soft buffer size depends on the UE radio access capability parameters. Processing time of UE for a certain MCS level and minimum inter-TTI interval (minimum time between two successive scheduling instants) can also be considered as capability parameters. These are signaled from the UE to the RNC by RRC protocol and further from RNC to Node B .
  • Radio resource signalling such as to prepare for or to carry out handover when changing the serving cell.
  • Other radio resource management information may also be scheduled in-between of data transmission. This signalling is usually of low rate, but has to be very fast to avoid packet or even call drops.
  • downlink messages are generally significantly larger than uplink messages since they typically include more parameters as described in more detail in 3GPP TSG RAN TS 25.331 "RRC Protocol Specification", V 5.0.0.
  • the signalling between RNC and UE using radio bearers mapped on dedicated channels is slow due to delays in the transport network between RNC and Node B and due to a larger TTI of dedicated channels.
  • signalling radio bearers configured for downlink interactive traffic with a peak rate of 2048 kbps is configured with a payload in RLC packets of 136 bits and a TTI of 40 ms, that is with data rate of 3.4 kbps.
  • signalling delay is 390 ms, assuming transport network delay of approximately 30 ms.
  • HSDPA TTI is equal to 2 ms and minimum inter-TTI interval is equal to 2 ms, signaling delay is 20 ms assuming 2 retransmissions per packet.
  • EP 1 207 647 A1 discloses a transport channel multiplexing method according to the preamble portion of claim 1.
  • the object of the present invention is consequently to avoid flushing of lower priority packets in the soft buffer of the UE when they are superseded by higher priority data.
  • the Node B receives low rate and delay sensitive data such as higher priority signaling, it will switch to the reserved or additional HARQ processes (if required), instead of using engaged HARQ processes which would cause the UE soft buffer to be flushed. Furthermore the Node B or RNC will signal to use a separate reordering queue for such data to avoid delays caused by reordering for in sequence delivery.
  • any HARQ process can be used for any priority queue.
  • it is proposed to restrict the use of HARQ processes.
  • Some HARQ processes may be limited for specific data flows of high priority, while other HARQ processes may maintain full flexibility.
  • Such HARQ processes of limited use will be called reserved HARQ processes. By this it is ensured that high priority data can be sent without waiting for completion of outstanding retransmissions or flushing the UE soft buffer of an HARQ process.
  • the number of HARQ processes is increased with respect to the minimum required by RTT to accommodate higher priority data.
  • additional HARQ processes which may also have limited functionality are in the following called additional HARQ processes. The limited functionality will most likely be caused by reserving smaller soft buffer sizes for additional HARQ processes. Thus, only some (lower) MCS can be scheduled with this processes.
  • Soft buffer memory that is required for one HARQ process depends on the following:
  • Fig. 9 plots soft buffer distribution among HARQ processes.
  • 5 HARQ processes may be configured to so to support higher TFRC or to support more reliable transmission (Incremental Redundancy instead of Chase Combining) - case b.
  • case c one process with unrestricted functionality (A1) and the other with restricted functionality (A2) in terms of maximum allowed MCS and/or transmission reliability are configured.
  • the following decision making rules may be envisaged for the embodiment of the invention assuming initial configuration of HARQ processes. If the soft buffer size of a UE is such that no HARQ process can be added, one HARQ process may be reserved. If the soft buffer size allows, the process can be added. In this case, the process may be configured only for certain (lower) TFRCs or may support less reliable transmission (Chase Combining instead of Incremental Redundancy), thus enabling more efficient use of the soft buffer for high priority and low rate data.
  • Additional HARQ processes also cause an increased signalling range for identifying the HARQ process to the UE.
  • the signalling of the HARQ process ID via a shared control channel is usually done by a fixed number of bits. Additional bits for the signalling may not be necessary because the number of HARQ processes that can be signalled is in the range of the power of two (e.g. 8 HARQ processes).
  • the method of configuring an additional HARQ process consequently requires that additional soft buffer memory is reserved for combining.
  • additional soft buffer memory is reserved for combining.
  • the soft buffer size for such limited HARQ processes is minimized. This is illustrated in query 400 with subsequent steps 420 and 440 in figure 7.
  • An additional advantage of adding an HARQ process resides in the fact that all ongoing regular HARQ processes are not affected and that consequently the data throughput is not reduced.
  • the transmitter pre-configures at least one reserved HARQ process for instantaneous transmission of delay sensitive data (step 340).
  • Variable RTT shall be monitored by the Node B in order to dynamically configure reserved processes. Furthermore, the state of the HARQ processes should be considered when scheduling high priority data in order to prevent soft buffer flushing. To avoid idle periods due to lack of available HARQ processes, it is necessary that number of HARQ processes is matched to the round trip time.
  • Round trip time dominantly depends on UE and Node B processing time, UE minimum inter-TTI interval and timing of the shared channels. While the HS-SCCH and the HS-DSCH in the downlink are shared channels, the ACK/NAK in the uplink are sent on a dedicated channel. The timing of the shared channels needs to be aligned with other UE's. Therefore there can be different offsets between the channels having an effect on the round trip delay. Finally, during the time between traffic bursts, continuous transmission supported by all HARQ processes is not necessary. In summary the number of HARQ processes to support data transmission depends on capabilities, configuration and traffic statistic and can also vary dynamically.
  • Node B will monitor RTT, traffic burstiness and QoS (required throughput) in order to estimate the number of processes that are necessary for transmission. Should the number be smaller than the one estimated at the time of process addition, these processes will be deleted and some of the remaining processes reserved for high priority data.
  • the soft buffer size of a UE is such that no HARQ process can be added, one HARQ process may be reserved. If the soft buffer size allows, the process can be added. In this case, the process may be configured only for certain (lower) MCS levels, thus enabling more efficient use of the soft buffer for high priority and low rate data. Decision process is depicted in figure 7 as described above.
  • Node B may use a separate reordering queue for some of reserved or additional HARQ processes.
  • reordering queues are tied exclusively to priorities of certain data flows. Priority is not the only cause for packet preemption. For example, even though some data flows have same priorities, some of the packets may be more delay critical than others. In this case it would be beneficial to route these packets to the HARQ process with a separate reordering queue. This avoids additional delay due to reordering. Therefore, having reordering queue per priority and having it per HARQ process are two possible options.
  • E/l bit denotes the options of explicit and implicit signaling. If explicit signaling of buffer allocation is used, soft buffer allocation (field Memory Partitioning) is sent as a vector whose length corresponds to maximum number of HARQ processes. If explicit signaling of reordering buffer allocation is used, a Reordering Buffer Configuration field is a vector of the same length denoting whether the reordering buffer is allocated per process or per priority. Implicit signaling is a default option in both cases and denotes uniform soft buffer partitioning and allocation of reordering buffer per priority respectively.
  • RTT variation of RTT shall be monitored by the Node B in order to dynamically configure reserved processes. If RTT decreases, smaller number of HARQ processes is needed. Thus, more functionality (higher maximum supported MCS, Incremental Redundancy instead of Chase Combining) can be allocated to additional processes. Should RTT increase, higher number of HARQ processes is needed. This, for example, may require further reduction in functionality of additional processes.
  • the invention discloses an intelligent method for a flexible configuration of multiple parallel hybrid ARQ processes.
  • the method minimizes the required buffer in the mobile station to store the soft values for combining while reducing the latency to transmit packets of different priority.
  • the latency is reduced without having to flush the bits corresponding to outstanding retransmissions in the soft buffer of the UE.
  • the invention enables efficient HARQ process configuration depending on UE capabilities and enables efficient soft buffer management in case of HARQ process addition. Further, the invention decreases the possibility of stalling in the reordering buffer by preventing the superceding of higher priority data by lower priority data and by configuring reordering buffer per HARQ process. By adapting the number of HARQ processes to the round trip time the use of the UE soft buffer is optimised.
